I have a Matco battery tool # BB 3B that uses a metal bar instead of brushes. It removes the terminal material well. I would guess with enough twists it would get the job done.
The other car looks like a Firebird or T/A to me. Notice the pop up headlights & pointed front end. The wheels also look like Firebird stockers also.
From what I know the shipper has to file the claim. Were thet insured through UPS? I think $100 is automatic & anything above that must be purchased.
When you compare the specs the AGM batterys always win. I'm waiting for my boat batteries to fail & then I'll be going with some. There is also a brand called Trojan that a lot of boaters talk about but, I don't know anything about them.
These guys are great to work with.

If they don't list the one you need call & talk to Mark. He is doing a custom one for my Megacab.
The reason for negative off first & on last is so that you dont touch your wrench to metal when removing the positive & get an instant welding lesson & blown fuses.
